DEVICE FOR APPLYING FLUIDS TO SHOES.

Specification of Letters Patent.

Patented Aug. 6, 1918.

Application filed February 11, 1916. Serial No. 77,754.

To all whom it may concern: I Be it known that I, Fnnonnrox M. FUR 131m, a citizen of the United States, residing at Revere, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Devices for Applying Fluids to Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to devices for use in applying to articles such as boots and shoes, in the process of their manufacture, relatively thick fluids such as enamel or 'cement, and is herein shown as embodied in fluid dispensing mechanism particularly adapted for use in machines for repairing imperfections in the surface of patent or enameled leather, such as the machine described in my prior Patent No. 1,096,423, granted May 12, 1914. It should be understood, however, that although the invention is of particular utility in a machine of this character, it is not thus limited in its applicability,.but is susceptible of a variety of uses other than those herein specifically men tioned.

An important object of the invention is to provide, in a device for dispensing relatively thick fluids such as patent leather repairing enamel, means for increasing above normal the tendency of the fluid to flow from the receptacle through the delivery outlet whenever the outlet valve is opened, in order that the required quantity of the fluid may be obtained at any time without undue delay. To this end, a feature of the invention consists in means of novel and improved construction for effecting a constant accumulation of fluid under pressure in the outlet portion of the receptacle, without, however, developing undue pressure when the outlet is closed. In the construction herein shown a cylindrical member is mounted for rota= tion within the receptacle in such manner as to carry toward the outlet the fluid that adheres to its periphery, and a deflector is arranged at one side of the outlet to remove or divert from the rotatable member the fluid that adheres to or is entrained thereby and cause this fluid to accumulate at the outlet. In this illustrative construction, moreover, the cylindrical member is so arranged relatively to the walls of the receptacle as to facilitate the development of pressure on the fluid in the outlet portion of the receptacle, aflording, however, sufficient provision for escape of the fluid to avoid the development of undue pressure when the outlet is closed.

For some kinds of work it is necessary or desirable to have at hand, ready for convenient use, fluids of different kinds orof different consistencies. In shoe repair work, for example, shoes with plain toes, in which the toe portion of the leather is relatively flexible, require for durability a thicker enamel than do the relatively inflexible box toes. It is accordingly a further object of the invention to provide improved fluid dispensmg means such as to enable the operator to use different fluids at will; and to this end a further feature of the invention consists in means for rendering different fluids constantly available for use under an increased outlet pressure without the danger of developing an undesirable pressure in any receptacle the outlet from which is closed.

Still another feature of the invention consists in the combination of a plurality of receptacles adapted to contain different kinds of fluid and each provided with an outlet, and means affording a single delivery passage or nozzle arranged to communicate selectively with the outlets of the different receptacles and having a delivery valve constructed to be opened by engagement with the work to which fluid is to be applied, thus affording the operator a choice of different fluids, while delivering the fluid at.

the precise point desired with reference to other portions of the machine and permitting unobstructed manipulation of the work presented to the nozzle.

The above and other features and objects of the invention, including certain details of construction and combinations of parts, will now be described with reference to the accompanying drawings and pointed out in the claims.

In the drawings:

Figure l is a perspective view of mechanism in which the invention is embodied, with portions broken away in order to illustrate more clearly the interior construction, this view illustrating the relation of the mechanism to other portions of a machine such as that shown in my patent hereinhefore referred to,

Fig. 2 is a side elevation, partly in section, of a portion of the mechanism. shown in Fig. l,

Fig. 3 is a section on the line 33 of Fig. 2, and

Fig. 4 is a view of the outlet nozzle and parts associated therewith.

The device includes a casting 2 which. may be supported upon the machine in any suitable manner not illustrated herein in detail, this casting being chambered to provide two fluid receptacles 4 and 6 separated by a partition 8, and having ledges 10 to support in inverted position bottles a and 5 containing fluid enamel of different kinds or consistencies. The enamel is thus permitted to drain from the bottles into the respective receptacles and to be held in the receptacles without undue exposure to the air. A cover 12 fits over a rim 14 on the casting 2 and is secured in position by means of a set screw 16, thus further protecting the enamel supply.

Bolted to the member 2 is a casting 18 which serves as a front closure for the receptacles 4 and 6 and is provided with out-- let passages 20 and 22 leading from the respective receptacles and communicating with a common delivery opening or passage 24. Valves 26 and 28 control the respective outlets 20 and .22 so that either outlet may be closed or opened irrespective of the other.

The opening 24, in the construction shown, is adapted to receive the tapered end 30 of the nozzle member 32 having a delivery passage 34 controlled by a gate .valve 36 pivoted at 38 and normally held closed by a spring 40. The novel features of construction of the nozzle member and the valve are not claimed herein, since they form the subject matter of another application Serial No. 750,303, filed Feb. 24, 1913. In the construction herein shown a valve 42 also is provided to control further the flow of fluid through the passage 34.

Mounted in hearings in the casting 2 and extending through the receptacles 4 and 6 a shaft 44 upon which are mounted in the respective receptacles cylindrical members 46 which may be formed as hollow drums or may have any other convenient or suitable construction. These members turn with their ends in close relation to the side walls of the receptacles and are of such diameter as to provide between their peripheral surfaces and the walls of the receptacles considerable spaces for the reception of the fluid. The shaft 44 may be driven in any suitable manner from other operative portions of the machine, so as to turn the members 46 in the direction indicated by the arrow in Fig. 2.

Opposite to the outlets 20 and 22 in the respective receptacles 4 and 6 are deflectors 48, each of which substantially closes the passage between the periphery of the member 46 and the wall of the respective re-' ceptacle, and is arranged to engage or to extend into very close relation to the peripheral surface of the member 46. These deflectors, in the construction shown, are conveniently formed as part of the casting 18. As the member 46 is turned in the dias rection of the arrow, the deflector 48 thus serves to 1 remove or divert from the periphery of the member the fluid that adheres thereto,- or is entrained thereby, and causes this fluid to accumulate adjacent to the outlet under a pressure which is greater than. normal by reason of the constant accession of fresh quantities of the fluid-in the outlet portion of the receptacle and the frictional drag upon the fluid in the direction of the outlet occasioned by. the rotation of the member 46. In order to facilitate the development of pressure in the outlet portion ofthe receptacle, the member 46 is.- mountedwith its periphery in close relation to the wall of the receptacle on the opposite side of the outlet from the deflector 48, thus nearly isolating from the remainder of the receptacle that portion which is adjacent to the outlet. The narrow passage 50,

however, between the member 46 andv the wall of the receptacle'afi'ords suflicient relief to prevent the development of an undesirable degree of pressure in the outlet portion of the receptacle when the outlet is 10 closed.

In the use of the device, suitable supplies of fluid, such as enamel of the required kinds or consistencies, are maintained in the respective receptacles 4 and 6, and the valves 5 26 and 28' are set to open one of the outlets 20 or 22 and close the other outlet in ac-' cordance with the kind of enamel which it is desired to use. When it is desired to apply'the usual small quantity of enamel to the surface to be repaired, the shoe is placed in contact with the valve 36 and the valve lifted in the manner described in my other application hereinbefore referred to. The shaft 44 meanwhile is constantly ro- '125 tated, and in consequence pressure is maintained in the manner above explained in the outlet portions of both receptacles, which causes the enamel to flow promptly and freely from the nozzle the moment the valve is opened. It will be evident, however, that by reason of the relief passages 50 the pressure at either outlet cannot increase above a certain small maximum irrespective of the opening or closing of the outlets or of the nozzle passage 3%. The invention consequently insures, during the operation of the machine, effective and prompt delivery of the required quantity of enamel, and permits the choice of difi'erent kinds of enamel with the same insurance of prompt delivery of either kind; and at the same time, no undesirable consequences are involved in the closure of the outlet from a receptacle for the time being not in use.

The construction herein described, com prising a single delivery passage or nozzle arranged to communicate with difi'erent fluid receptacles, has an important advantage, particularly in a machine of the type herein referred to in which the delivery of the fluid is controlled by a valve arranged to be opened by engagement with the work. It is essential to the most efficient use of a machine of this character that the fluid be delivered at a point as near as POSSIblB lJO other operating instrumentalities to whlch the work is to be subsequently presented. If the machine, however, were provided with a separate delivery nozzle for each receptacle, both nozzles could not be located near enough to the desired point to satisfy the above mentioned requirement, since such an arrangement would position the nozzles so near to each other that when the work were pressed against one of the valves to receive the fluid at the point required, the other valve also, unless great carevere exercised, would be likely to be engaged and opened by the work, and either nozzle and valve would obstruct the free manipulation of the work presented to the other nozzle. The dispensing device constructed in accordance with a feature of this invention, includlng a single valve controlled delivery passage or nozzle which may be put in communication with difierent fluid receptacles, permits the fluid to be delivered at the precise point desired and imposes no restriction upon the free manipulation of the work, while at the same time rendering it possible to use different fluids at will.

Although the invention is disclosed herein as embodied in mechanism having the spe cific features of construction shown and described, it should be understood that various detailed embodiments are comprehended within the scope of the invention as defined in the claims.
